Replying to Mounting patterns or cast on park skis

So I currently have a pair of 4frnt Devs mounted with marker griffons and I want a backcountry setup but can't justify getting another pair of skis and pin bindings. I will only be in the backcountry roughly 5 days a season. Anyway, I was wondering if it would be possible to remount my devs with a cast system at the same mount point or if I would have to adjust the mount point. And if I can't remount my Devs with a cast system then would mounting a pair of chronic 94's with Cast be a bad idea because of lack of edge in the backcountry?
I have also been looking into Daymakers touring adapters but IDK how I feel about them
